A new study, executed by researchers from the University of Texas at Austin, US, finds that air pollution shortens life expectancy on the global level by up to two years and the situation worsens every year.
For the study, a team of the researchers looked at tiny PM2.5 particles that come from such sources as power plants, exhaust systems, airplanes, forest fires, and dust storms. These particles, due to their small size, stay in the air longer than the heavy ones and get deep into the lungs.
Dr. Joshua Apte, an assistant professor in the department of population health at the University of Texas at Austin, says: “The overall impact of air pollution is big and what we’re doing is putting the health benefits of addressing air pollution into context. For example, it could lead to a life expectancy that’s equivalent to or greater than curing certain import cancers like lung cancer and breast cancer.”
A new research, published in the Journal of Internal Medicine, finds that consuming more fish and long-chain omega-3s reduces total mortality. However, scientists insist that not all cooking methods are good for that matter.
For the study, a team of researchers performed an analysis of data from NIH-AARP Diet and Health study, which included information on the dietary habits and health of 240,729 men and 180,580 women followed for 16 years.
The authors conclude: “Consumption of fish and [omega-3s] was robustly associated with lower mortality from major causes. Our findings support current guidelines for fish consumption while advice on non-frying preparation methods is needed.”
Cigarette smoking considered to be the largest risk factor for morbidity and mortality in developed countries. Nevertheless, according to the national studies, it tends to decrease in the recent decades. But there are also other risk factors coming into a view. Here are 5 things in your everyday life you should pay attention to avoid health risks:
Loneliness reduces lifespan by the equivalent of smoking 15 cigarettes daily, according to a research from Brigham Young University.
Sitting increases people’s risks for colon, endometrial, and lung cancer.
Poor sleep is considered as a risk factor for cardiovascular disease.
Indoor tanning increases the risk of skin cancer.
A poor diet high in sugar, processed foods, and saturated fats expose people to potentially fatal diseases at similar rates as smoking.
A new study, published in the journal of the American Geriatrics Society, suggests that older adults that leaving home every day have more chances to live longer compared to those who stay indoors.
The study included data of 3,375 adults aged between 70 and 90 years all of whom were involved in the 1990–2015 Jerusalem Longitudinal Study.
Having analyzed the received data, the scientists found that senior adults who left their houses regularly were at the lowest risk of death, while those seniors who left their houses seldom were at the highest risk of death.
Dr. Jacobs says: “What is interesting is that the improved survival associated with getting out of the house frequently was also observed among people with low levels of physical activity, and even those with impaired mobility. Resilient individuals remain engaged, irrespective of their physical limitations.”
